On Wednesday, sources told CNN that Attorney General William Barr will announce the completion of Special Counsel Robert Mueller's probe "as early as next week." Now, a senior Justice Department official is telling NBC News that's not quite true.

Mueller has been investigating potential ties between the Trump campaign and Russian election interference for nearly two years, and has levied indictments against or negotiated plea deals with 37 people. Still, as NBC News reported Friday, the Justice Department isn't expecting to hear everything from him next week. And when Mueller does drop the details, Barr will still have to read it and write a summary of the confidential report that he'll give to Congress.

If you're still itching for details, Mueller's sentencing memorandum in his case against ex-Trump campaign chair Paul Manafort is due Friday at midnight. The report will contain pretty much everything prosecutors want a judge to know before Manafort's March 13 sentencing, CNN notes.
